Answer 1

Iron sulfate (FeSO₄) is composed of the iron ion (Fe²⁺) and the sulfate ion (SO₄²⁻). In this compound:

• The bond between iron (Fe) and the sulfate ion (SO₄) is ionic. Iron donates electrons to form a positively charged ion, while the sulfate ion is negatively charged.

• Within the sulfate ion (SO₄), the sulfur (S) and oxygen (O) atoms are covalently bonded. The sulfur atom shares electrons with the oxygen atoms to form the sulfate ion structure.

Therefore, the correct statement is: Fe and S are ionically bonded, while S and O are covalently bonded.
